That’s determined by your products/services and objectives.  At a high level, most websites have separate pages for Home, About, and Contact, and separate pages for each of your key products or services.  For example, an Auto Body Shop would have a separate page for Auto Body Work and Auto Glass Replacement, but maybe their other services are “secondary” so they do not need separate pages for them, such as brake or tire repair.  In general, if you want your services to rank well with search engines, they should have their own page.  We can assist with this.
